Abstract
A transreflective display in which the thickness of the liquid crystal layer is the same for both transmissive and reflective modes. The transmissive and reflective pixels are stabilized in two different liquid crystal configurations with different birefringences. The light retardation effect of one path in the transmissive pixels is close to or equals the retardation effect of two paths in the reflective pixels, resulting in synchronization of the two modes.
